' To all whom it may concern:

Be it known that I, JOHANN ROTTKAMP, a subject of the Emperor ofGermany, residing at Cologne-on-the- Rhine, in the Province of'Rhineland, Germany, have invented certain new anduseful Improvements inHorseshoes, for 'which I have received Letters Patent in Belgium,No.152,288, dated January 20, 1906, and Luxemburg, No. 6,260, datedFebruary 26, 1906; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

For the purpose of effectually preventing horses from slipping orfalling on smooth roadways a number of devices have already beenemployed in connection with horse-shoes, as for example inlaid andunderlaid pieces of india-rubber. These however do not fully meetrequirements as they are only adapted for receiving the entire pressureof the animals foot while in the case of side pressure that is to say inthe case of the horse actually slipping they do not act. Thesedisadvantages completely obviated by the present invention, according towhich the horse-shoe is made in two parts like the known horse-shoes ofa similar kind, one of these parts consisting of a plate fixed on allsides of the hoof and the other of an iron tread-piece fixed to suchplate.

The novelty of the present horse-shoe consists in the plate which isattached to the foot and furnished with a claw-like tread-rim providednearly in the middle with a screw against which a second plate lyinginside the tread-rim is movably attached and when the horse slips, movesback partially behind the claws of the treadrim, so that the claws cancome in contact with and take hold in the ground. Thereby slipping onsmooth surfaces such as asphalt paving or paving covered with ice iseffectually prevented.

The invention is illustrated in the accompanying drawings in which:Figure 1 is a view of the upper side of the plate to be attached to thehorses hoof. Fig. 2 is i a side view of this plate. Fig. 3 is amodification of the plate. Fig. 4 is a longitudinal section of Fig. i.Fig. 5 represents a view of the under side of the iron treadpiece andFig. 6 is a longitudinal section of Fig. 5. The Figs. 7 and 8 arelongitudinal sections of the horse-shoe, showing the two parts connectedtogether in their positions, when the horse is moving in the ordinaryway and when it is slipping.

A thin plate a (Fig. l4) of steel or tempered iron of the same shape asthe horse hoof, which may, as is shown in Fig. 3, be provided with a rim1), has on its edge a number of sharp-edged claws c, which run downwardsl at right angles to the plane of the plate.- This plate a, which isattached to the horses hoof by means of horseshoe nails, is providedwith the extensions (1, d, c, which are partially covered by two disksff, fastened by rivets to the middle extension 0. In consequence of thisarrangement it is possible to [it exactly the plate to the shape of thehorses hoof.

The middle extension 0 bears a collar 9, into which a screw-pin 71 witha rounded head is screwed. By means of this pin the actual tread plate1', which may be in the form of the grooved iron with tow packing,illustrated in Figs. 5 and 6 is fixed so that with the aid of thedisk-like excision n it can oscillate around the head of the screw.

The part i is provided with extensions or flanges is, It, Z, which arein the same manner as the extensions (Z a of the plate a, covered bydisks m, m, riveted to the middle extension 1. Between the parts a and tan india-rubber ring 0 is inserted.

The action of the device is as follows: When the horse is moving in theordinary way, it treads uniformly on the tow lining of the part 1',without any oscillation of the plate arising; consequently the claws 0cannot come into action. If, however, the animal slips, for exampleforwards (Fig. 8), the part i is pressed inwards, the claws in front ofthe part t come in contact with the roadway and thus recover the holdlost by the horse. I

A similar action takes place if the horse slips in another direction.

A further advantage of the new horse shoe is that the horse providedtherewith always has a flexible tread and thus does not become foot-soreand the possibility of injury to the horse by moving over asphalt pavingis impossible as when the animal is moving in the ordinary way the clawsdo not come in contact with .the ground.

What I claim and desire to secure by Letters Patent, is

1. A horseshoe. comprising a shoe-plate for attachment to the hoofprovided with a projecting rim, :1 tread'plate. ind meins for connectingtogether the said plates pivotally at their middle parts so that thetrend-plate is free to oscillate on all sides within the said rim.

2. The improved horse-shoe consisting of two parts. a horse-shoe plate uattached to the horses hoot and fun nished with a ela\\'likc rim (2 anda trend-plate i. fixed to the plate (1 by means of a screw 7: andcscilL-rting on all sdes inside the rim around the head of the screw.

In testimony whereof I have aiiixezl my signature. in presence of twowitnesses.
